Description

  In the present invention, in recent years, living learning has been proposed as means for improving academic ability, and children are often learning at a dining table. Therefore, the present invention relates to a dining chair that can also be used as a learning chair that can adjust the seat plate according to the growth of school children so that it can be adjusted to the height of the dining table.

  There is a chair that allows the seat board to be moved up and down because a growing school child's learning chair initially grows quickly even if purchased according to the body shape (patent document 1).

  However, in the case of a dining chair, it is difficult to use simply by adjusting the height of the seat plate.

  In addition, an optimal dining chair based on ergonomic data that takes into account the child's height, the distance between the elbow and the seat, the distance from the back of the knee to the buttocks, and the distance from the back of the knee to the heel is desired.

  Therefore, there has been a demand for a learning chair for a dining chair that not only adjusts the height of the seat and footrest but also allows the seat to move back and forth.

Utility Model Registration No. 2562663

  In order to provide an optimal dining chair based on ergonomic data, the present invention can not only easily adjust the height of the seat and footrest according to the growth of the child, but also the seat can be moved back and forth. It is what I did.

  By doing in this way, the learning chair for dining chairs suitable for the growth degree of a child can be provided.

  In order to solve the above-mentioned problems, the present invention comprises a seat plate portion, a backrest portion, a front leg, a rear leg, and an armrest portion, and the seat plate is moved upward and also moved backward. It is characterized by.

  A seat plate that has an armrest with a backrest erected on the upper ends of a pair of left and right front legs obliquely in the rear direction, a rear leg is obliquely formed near the end of the armrest to form a leg body, and a seat plate is fixed The base is screwed between the front and rear legs.

  In addition, it is characterized in that it can be used from infants to children by allowing the footrest to move up and down.

  Since this invention is such a structure, since not only a seat board part but a footrest part can be adjusted, the dining chair suitable for a child's growth can be provided.

  Further, by integrating the front leg with the armrest, the depth can be adjusted simultaneously with the height adjustment of the seat plate.

  Thus, since the present invention can change the depth of the seat plate simply by changing the vertical position of the seat plate, it is possible to provide a dining chair according to the growth of the child.

  An embodiment will be described with reference to the drawings. In FIG. 1, 1 is a seat plate part, 2 is a backrest part, 3 is a footrest part, 4 is an armrest part, 5 is a front leg, 6 is a rear leg, and 7 is a front part. Nuki, 8 is a post-run.

  The seat plate portion 1 has a cushion covered with a cover disposed on the seat plate base 11. The seat plate base 11 is screwed between a front leg 5 in which the armrest portion 4 is obliquely installed in the rear direction and a rear leg 6 in which the armrest portion 4 is obliquely provided.

  A backrest 2 is erected and fixed to the upper end of the armrest 4.

  The footrest 3 is installed below the left and right front legs 5, 5.

  The front through 7 is constructed between the left and right front legs 5 and 5. The rear penetration 8 is constructed between the left and right rear legs 6, 6.

  In the front leg 5, footrest mounting holes 71 are arranged at a constant pitch.

  In the armrest 4 and the rear leg 6, screw holes 44 and 66 are arranged in a corresponding row at a constant pitch.

  The footrest portion 3 has an L-shaped cross section. However, when a person who is short like an infant uses it, the seat plate moves backward to raise the seat plate upward. For this reason, the footrest portion 3 also moves upward, but the leg may not reach if the footrest portion main body is in front. Therefore, as shown in FIG. 2, the foot can be reached by rotating 180 degrees so that the bottom surface becomes the top surface and fixing.

  The front and rear legs have a lateral C-shape so that there is a sense of stability. When the seat plate portion 1 is fixed upward, the center of gravity of the seat plate portion moves rearward, but the rear leg 6 is provided in the vicinity of the upper end of the armrest portion so that it does not become unstable.

  Since the backrest 2 is curved so as to wrap around the back, there is a sense of security.

    If one of the mounting holes of the base plate base 11 is a long hole 12, if only one mounting hole is fixed to the fixing hole of the front leg or the rear leg, the other hole moves only in the lateral direction and is easy to fix.

  It is the perspective view seen from the front direction of this invention.   It is a side view of this invention.
